Abstract
A window whose light transmission can be mechanically controlled and varied smoothly from a high value of approximately 40% to a low value of approximately 1% is achieved without the requirement of rotation. Polarizing molecules are coated onto four different surfaces in particular patterns. When the coated panels are assembled in the disclosed manner light transmission can be modified with only small translational movements. Durability benefits are also achieved, as well as the potential for lowered heat transmission.
